When it comes to bandwidth
and speed, cable broadband is the one who wins the battle. Cable is
capable of offering a speed that is almost 2 times faster than ADSL.
However cable services can slow down if too many people are accessing
the internet at the same time in the same region. With ADSL this is not
the issue, even if you and your neighbour are using the internet at the
same time, it does not considerably affect your browsing speed.
Nonetheless, the speed and bandwidth battle is always won by the Cable Broadband.

Installation:This is the next important factor to
be considered when a type of broadband service is to be taken. With
cable service all you need to do is call the cable technician to get a
new line installed. Next you just need to connect this line to your
modem; it is as easy as plugging your VCR to the television.

Theoretical vs Real
times:

So many factors go into real
transfer times that it is very difficult to wrap blanket numbers around
them. Once you get over ISDN speeds, network latency, protocol
overhead, driver efficiency, and all kinds of other technical things get
in the way. In general, expect transfer speeds of 40 to 80% of the
maximum speed.

About the Analog-Digital Transition; and problems that Exist.The digital transition
wasn't created a couple of years ago. It's been scheduled for over a
decade. Yet, manufacturers still produced analog televisions as late as
2006. Back then the
transition was scheduled for 2006 - changed to the 2009 date after the
FCC realized that the nation wasn't ready. Stores are now required to
put a sticker on analog TVs letting people know about the transition.
That would've been nice to do a few years ago before people spent their
hard-earned money on an analog TV.

Aspect Ratios:

The problem is that high definition video has a
16:9 aspect ratio. All other TV programming is 4:3, which is the
square-like image that we’ve watched most of our lives.

The
problem is that HDTVs are 16:9, so a 4:3 image will either have black
bars on the sides of the screen or the image will stretch to fill the
entire screen. Black bars on the side of a screen is one thing but
getting used to a distorted image is difficult, especially when you
expect your digital TV to display a better image than your analog TV.

Analog Signals Absent in Digital Boxes:The problem is that many of the digital converter boxes offered by the
NTIA's coupon program do not receive analog signals. This is an issue
because low-power or Class A stations will continue in analog after
February 17, 2009.

For example, if you live in a city that has a
low-power station and you use a digital converter box that doesn't
pickup analog then you will lose access to that signal unless you
disconnect the box and plug the antenna going directly into the TV.
